Railroad Tie.
No. 235,078. Patented Dec. 7,1880.
N PETERS PNOTO-LITHOGRAPNER, WASHINGTON- D. C.
UNITED STATES GEORGE H. GILMAN, OF BLISSFIELD, MICHIGAN.
RAILROAD-TIE.
SPECIFICATION forming part of Letters Patent No. 2 35,0'78, dated December '7, 1880.
Application filed August 3, 1880.
.To all whom it may concern:
Be it known that I, GEORGE H. GILMAN, of Blissfield, in the county of Lenawee and State of Michigan, have invented certain new and useful Improvements in Railroad-Ties; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
Figure l is a perspective view of one end of my improved railroad-tie. Figs. 2 and 3 are cross-sections taken, respectively, on the lines 3 and z in Fig. 7. Fig. 4 is a top view. Fig. 5 is a side view. Fig. 6 is a top view of the tie, the rails and locks having been removed, and Fig. 7 is a bottom view.
Corresponding parts in the several figures are denoted by like letters of reference.
This invention relates to metallic railroadties; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claim.
My improved railroad-tie, which is made of cast-iron, consists of a rectangular plate E, concave upon the under side, as shown at G, and provided with longitudinal strengtheningribs F F, which extend downward on a plane with the bottom of the sides of the tie, thus forming additional supports for the same.
Upon the upper side of the tie, near each end, are formed flanges B B, extending entirely across the upper surface of the tie, and curved inwardly to receive and hold the outer sides of the rail-flanges, the inner sides of which are fitted adjoining the studs I 1, formed for this purpose upon the tie.
G is the removable lock-plate, which is secured upon the tie by means of a vertical bolt,
K, and nut L, just above the inner side of the rail-flange, thus holding the rail securely. A
(No model.)
stud, J, formed upon the tie on theinner sides of the studs I I, enables the lock to be instantly adjusted in proper position without danger of displacement, while said studs I I, between which the locking-plate fits, prevent any lateral movement of the plate.
D is the slot in the tie through which the bolt K is passed.
From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood.
By making the under side concave, and providing it with the ribs F F, the metal is saved, strength is insured, and the tie is caused to rest firmly and safely upon the foundation.
The means for securing the rail upon the tie are simple, safe, and effective, and permit the rail to be readily removed when necessary.
I am aware that many railroad-ties are constructed with concaved or beveled portions strengthened by ribs in order to secure lightness with durability, and such I do not wish to be understood as claiming, broadly, as of my invention. Therefore,
What I claim is 'lhe herein-described cast-metal railroad-tie, made concave on its under side, and having longitudinal strengthening and supporting ribs F F, and upon its upper surface transverse inwardly-curved flanges B B, extending entirely across the tie, studs I I, for preventing lateral movement of the locking-plate G, studs J, and slots 1), as and for the purpose specified.
In testimony that I claim the foregoing as my own-I have hereto affixed my signature in presence of two witnesses.
GEORGE E. GILMAN.
Witnesses JOHN J. CLARK, JNo. FULLER.
